Abstract

A control method is provided for an electronically controlled damping system in a vehicle, wherein at least one characteristic quantity varying with different axle load conditions of an axle of the vehicle is determined, a correcting variable is established for an actuator of a vibration damper based on the characteristic quantity and the correcting variable is transmitted to the actuator of the vibration damper to adjust a desired damping behavior of the vibration damper.
